dc42d031fb Revert "Revert "Remove the darwin gdb option, that version of gdb is now dead and the rest of the compatibility should be done on a dwarf-N level.""
This reverts commit r189913.

Talked with Eric on IRC. I am going to XFAIL the failing test since it
is using what Eric described as "the member hack" which was needed on
that old GDB.

Sorry for the noise!

a9b2c79e26 Have the skeleton compile unit construction method take the CU it
is constructing from as an input and keep the same unique identifier.
We can use this to connect items which must stay in the .o file

duplicate unique numbers for the sections and needing to do lookups
based on MDNode.

We currently emit labels with the prefix Lllvm$workaround$fake$stub$ if
the target's MCAsmInfo has getLinkOnceDirective() mapped to something
interesting.  This was apparently a work around introduced in r31033 for
binutils that we don't need anymore.

d7d43dc435 DebugInfo: Do not use the DWARF Version for the .debug_pubnames or .debug_pubtypes version field
Summary:
LLVM would generate DWARF with version 3 in the .debug_pubname and
.debug_pubtypes version fields.  This would lead SGI dwarfdump to fail
parsing the DWARF with (in the instance of .debug_pubnames) would exit
with:
dwarfdump ERROR:  dwarf_get_globals: DW_DLE_PUBNAMES_VERSION_ERROR (123)

This fixes PR16950.

f04e4efcaa Turn on pubnames by default on linux.
Until gdb supports the new accelerator tables we should add the
pubnames section so that gdb_index can be generated from gold
at link time. On darwin we already emit the accelerator tables
and so don't need to worry about pubnames.
